- 摘 要：通过温室内田间小区试验，在固定的灌水周期情况下研究了不同灌水定额对秋冬茬青椒生长、产量及水分生产效率的影响，以确定青椒的适宜灌溉制度，为日光温室秋冬茬青椒膜下滴灌合理灌溉提供科学的参考依据。结果表明：当灌溉定额在一定范围内时，青椒株高、茎粗随着灌水定额的增大而增大，但当灌溉定额超过280 mm时，灌水将抑制青椒的生殖生长，导致青椒产量下降，水分生产效率降低；当灌溉定额为260 mm时，产量和水分生产效率最高。

- Abstract:Through a field experiment in the greenhouse,different irrigation quota in the case of a fixed irrigation cycle impact on green peppers growth,yield and water productivity in both autumn and winter were studied，to determine the suitability of irrigation regime.The results showed that when irrigation quota within a certain range，the height and stem diameter of green pepper with the increase of irrigation quota；but when irrigation quota was too large to reach 280 mm,irrigation would inhibit the reproductive growth of green pepper，cause peppers lower production,reduce water use efficiency；when irrigation quota was 260 mm,yield and water use efficiency were the highest,could be used as indicators of appropriate irrigation for drip irrigation of green peppers.
